CEREC 3D全瓷嵌体与复合树脂嵌体修复后牙Ⅱ类洞的疗效比较
|
摘要
目的:探讨陶瓷重建修复(CEREC)3D全瓷嵌体与复合树脂嵌体修复后牙Ⅱ类洞的疗效差异。方法:按照随机数字表法将84例(108颗)后牙Ⅱ类洞患者分成研究组(56颗)和对照组(52颗)各42例。研究组予以CEREC3D全瓷嵌体修复,对照组则予以复合树脂嵌体修复。比较两组治疗后1年时嵌体修复效果[以改良美国公共卫生署(USPHS)标准为评估依据]差异,记录其治疗6个月、12个月、18个月时预后效果(磨耗情况、邻接关系、嵌体颜色、继发龋齿、嵌体折裂、嵌体脱落等)评估结果差异。结果:治疗后1年时,两组USPHS评估结果显示:研究组边缘密合性、嵌体外形、牙体完整性及牙龈健康情况A级率均明显高于对照组,差异均有显著性。治疗6个月时,两组嵌体磨耗情况、邻接关系、嵌体颜色、继发龋齿、嵌体折裂、嵌体脱落等预后指标A级率比较,差异均无显著性;治疗12个月、18个月时,研究组上述预后指标A级率均明显高于对照组,差异均有显著性。结论:CEREC 3D全瓷嵌体对后牙Ⅱ类洞的修复效果及预后效果均较复合树脂嵌体突出,临床可将其作为一种可行性治疗途径为患者获得更理想的治疗效果提供条件。
Objective To compare the effects of chair-side economic reconstructionof esthetic ceramic(CEREC) 3 D allceramicinlays and composite resin inlays in restorations for backteeth typeⅡcavity. Methods By the random number table method, 84 cases(108 teeth) with backteeth typeⅡcavity were divided into study group(56 teeth) and control group(52 teeth), 42 cases in each group. The study group was treated with CEREC 3 D all-ceramic inlays for restoration, and the control group was treated with composite resin inlays for restoration. The restoration effects [referring to modified United States public health service(USPHS) standard] were compared between the two groups at 1 year after treatment. The prognosis(wear, adjacency, color of inlays, secondary caries, inlay fracture, inlay off) was recorded at 6 months, 12 months and 18 months after treatment. Results 1 year after treatment, the evaluation results of USPHS showed that the edge adaptation, shape of inlays, tooth integrity and grade A gingival health rate in study group were significantly higher than those in control group. After 6 months of treatment, there were no significant differences ingrade A prognosis rate between the two groups. After 12 months and 18 months of treatment, the grade A rates of above indexes in the study group were significantly higher than those in the control group. Conclusion The restoration effects and prognostic effects of CEREC 3 D all-ceramic inlays are more significant than composite resin inlays in restorations for backteeth typeⅡcavity, which can be used as a feasible treatment.
